Brick vault house

This house was designed by the Spanish firm, Space Popular. It was completed last year in Santa Barbara, Spain. Two things, in particular, make it unique: (1) Its exposed steel structure (12x12 grid) and (2) its brick vaults. But both of these things really serve one idea. They express the building's structure. And that's about all you need for good architecture -- one clear idea. All photography by Mariela Apollonio.
